Blind Postman EN United States

You can see only walls. You cannot stop until you hit an obstacle. Obstacles can be dangerous. Obstacles can be helpful. You won’t find out until you try. What is it glowing in the distance? It’s a letter! You have to reach it. You have to gather it and bring it to the end. Can you die? No! It’s just another try. You will try until you find an exit of the labyrinth.
